Accepted Medicare and Medicare Advantage Plans

Below is a listing of the Medicare and Medicare Advantage plans purchased as an individual where NorthBay Health is considered in-network. This does not reflect any plans offered through an employer/retiree plan.

Health Plans for 2025:

Special update for Aetna Medicare Advantage PPO individual plans:

  • Both our hospitals are out-of-network.
  • Starting 5/1/2025: our primary care doctors and specialists will be out-of-network.
  • If you have out-of-network benefits: You can continue seeing NorthBay Health doctors and receive treatment at both our hospitals with higher co-pays and an out-of-pocket maximum.

Special update for UHC Medicare Advantage plans:

  • You will need to enroll through our partner Meritage Medical Network to see a NorthBay Health primary care doctor under a UHC Medicare Advantage plan. UHC Medicare Advantage and Medicare are not permitting enrollment into this group
  • Our primary care doctors are not available through Hill Physicians Medical Group and UHC Medicare Advantage. You will need to select a different primary care doctor. Referrals are accepted into specialty services.

Don't see your plan listed?

If you do not see your plan listed here, it means either:

  1. Our hospital group (NorthBay Health Medical Center and NorthBay Health VacaValley Hospital) is not in-network.
  2. Our medical group is not in-network.
  3. Our hospital and our medical group are not in-network.

If you have a Medicare Advantage PPO plan, and you have out-of-network benefits, you can be seen and you will have a higher out-of-pocket cost.

Why choose a Medicare Advantage plan?

Medicare Advantage plans offer more benefits than Original Medicare including prescription drug coverage (Part D), and others such as dental, vision and over-the-counter allowance.

If your current plan doesn't offer the benefits and features you are looking for, it may be time to switch to a new Medicare plan.
